Switching the Load Balancing Algorithm

If you configure one or more origin server addresses, you can use a load balancing algorithm to distribute traffic across these origin servers. WAF supports the following algorithms:

Origin server IP hash: Requests from the same IP address are routed to the same backend server.
Weighted round robin: All requests are distributed across origin servers in turn based on weights set to each origin server. The origin server with a larger weight receives more requests than others.
Session hash: Requests with the same session tag are routed to the same origin server. To enable this algorithm, configure traffic identifiers for known attack sources, or Session hash algorithm cannot take effect.
